' To (til whom, it may concern:

' of the salient features of which is the Be it linown that I, ETHA'N It Dorms, acitizen of the United States, residing at Pullman,-

in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cast Met-al Side Frames for Trucks, of which the following is a specification. v y

In order to provide a cast-metal side for a railwaycar truck which shall combine strength, light weight, and a pleasing appearance, I have invented a structure an approved forrn of which is described below, one

rowsion of hollow ribs extending over an part way down the sides of the pedestal portions.

Another object of my invention is'the provision in the truck sides of-means .to ermit theready attachment of rods or the ike .to keep the journal-boxes and axles from leavingthe sides in case the car becomes overturned and to tie together the two limbs of each pedestal portion.

In the accompanying drawings I have illustrated the'preferred mechanical embodiment of my invention, wherein Figure 1 isan elevation of a side frame fora car-truck. Fig. 2 is a plan view of the structure shown in Fig. 1; and Fig. 3 is a vertical cross-section on line 3 3 of Fig. l as viewed in the direction indicated by'the arhole 13 passing through the side and recess at each end. The lower end of the outer .limb of each pedestal portion 21 is supplied with a similar enlargement 14, having a recess 15 and transverse hole 16. A rod or similar device 15 (not shown)'-may be inserted in,

these recesses to prevent the journal-boxes and axles from leaving the side in case the car b ecornes upset and to tie the edestal por-.

trons together, the bar being he (1 place by,

means of pins or bolts passing through holes 13 and lGJ Plate portion 10 is alsolsupplied with an integral top flan e 18, extended 'outwardly from eachside t er'eof, vertical'ribs 19 joining the flanges 11 and 18 on each side of the main plate or web. Tapered hollow ribs 20, the main portion of each of which is cylindrical in crosssection, extend from the junctions of bottom flange 11 and end ribs 19 diagonally upward and over the pedestal portions 21, each rib projecting from both sides of plate portion 10 and extending part way down the outer side of its pedestal, as at 20 Ribs 20 are tied together by the integral upper flange 18, and each is also supplied on its inner side with'a plurality of holes 22, which are used when the side is cast to support the cores of the ribs and through which the cores maybe afterward removed. Avertical rib 23 joins the outer end portions of each rib 20, with the adjacent enlargement 14 at the lower end of thepedestal, and each pedestal is also provided with a hollow springcap portion 24, as is clearly shown-in Figs. 1 and 3: Bolts 25 are employed toiasten the transverse transoms (not shown) to the sides of the truck, and the tie-plates 26 and 27- are riveted to the tops and bottoms f the side frames on opposite sides of the truck, for the purpose of securing them together.

It'is to be understood thatthe parts of each side are all integral and that the structure is produced by casting, whereby an economically-manufactured side frame results, having its metal disposedtoattain a maximum of strength.

I claim 1. A side for a car-truck having pedestals,

a web or plate portion integral with and connecting said pedestals, and hollow ribs on said web or plate portion and integral there with, each extending over one of said'ped estals, substantially as described. 2. A side fora car-truck having pedestals, a web or plateportion'integral with and connecting 'said pedestals, and hollow ribs on said web or plate portion and integral'therewith, each extending over and part way down the outer side of one of said pedestals, substantially as described.

3. A side for a car-truck having pedestals, a web or plate portion integral with and con necting' said pedestals, and hollow'ribs each' integral with and projecting from both sides of said web or plate portion and extending over one of said pedestals, substantially as described.

4.. A side fora car-truck having pedestals, a vertical web or plate portion connecting. said pedestals having top and bottom flanges and hollow ribs, each of the latter extending from said lower flange over one of saidpedestals, said top flange connecting said hollow ribs, substantially as described.

5. A side for a car-truck having pedestals,

a web'or plate portion integral with and connecting said pedestals, said portion having integral therewith top and bottom flanges extending from both sides thereof, vertical ribs on each side of said Web or plate portion joining said top and bottom flanges, and hollow ribs, each projecting from both sides of said web or plate portion and extending over one of said pedestals, said top and bottom flanges connecting said hollow ribs, substantially as described. 1

'7. A cast-metal side for a car-truck having pedestals, a Web or plate portion connecting said pedestals l'iaving top and bottom flanges, a pluralit of ribs connecting said flanges, and hollow ribs joined to the junctions of said bottom flange and the outer ribs, each extending over one of said pedestals, substantially as described.

8; A cast-metal side for a car-truckhaving pedestals, a web or plate portion integral with and connecting said pedestalshaving integral top and bottom flanges, aplurality of integral ribs connecting said flanges and integral hollow ribs joined to the junctions of said bottom flange and the outer ribs, each extending over and part way down the outside one of said pedestals, substantially as described.

9. A side for a car-truck having pedestal portions integral therewith and a recess in each of the two limbs of each pedestal portion extending upwardly from the lower surface thereof for the reception of means to prevent the carnal-boxes and axles from leaving the side and to tie the two limbs together, substantiall as described.

10. A side for a car-truck having pedestal portions integral therewith and a recess in each of the two limbs of each pedestal portion for the reception of means to prevent the journal-boxes and axles from leaving the side and to tie the two limbs together, said side being provided with transverse holes therethrongh, each intersecting one of said recesses, substantially as described.
